Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation screens, in particular to a high-efficiency sound absorption and insulation screen. Background Art

[0002] A sound insulation screen is a sound insulation facility that is inserted between the sound source and the receiver to block the direct sound between them. This allows for a significant additional attenuation of the sound wave propagation, thereby reducing the noise impact within a certain area where the receiver is located. Sound insulation barriers are mainly used outdoors. As road traffic noise pollution becomes increasingly serious, some countries have adopted a large number of various forms of barriers to reduce traffic noise. The function of a sound barrier is to prevent the propagation of direct sound, isolate transmitted sound, and provide sufficient attenuation for reflected sound. Therefore, the sound insulation and attenuation of a sound barrier is designed based on the principle of sound wave reflection.

[0003] When installing sound insulation screens on both sides of a highway, H-shaped steel is usually fixed to the concrete crash barrier, and then a sound-absorbing sound insulation screen or a transparent sound insulation screen is sequentially placed into the groove of the H-shaped steel upright. Then, a sound-absorbing sound insulation board is installed at the bottom of the sound insulation screen to block the gap between the bottom of the sound insulation screen and the concrete crash barrier. However, when installing the sound insulation screen, multiple sound insulation screens are placed on both sides of the H-shaped steel, and a gap is easily generated between the upper and lower sound insulation screens, which will affect the sound insulation effect of the sound insulation screen. In order to achieve the purpose of tightly fitting the sound insulation screens, a high-efficiency sound-absorbing sound insulation screen is provided. Utility Model Content

The sound insulation screen body 4 and the sound-absorbing and sound-insulating board 5 are installed by an installation mechanism 6; the installation mechanism 6 includes a connecting block 601, which is fixedly connected to both sides of the sound insulation screen body 4, and the inner wall of the vertical pole 2 A movable groove 602 is provided, and the inner wall of the movable groove 602 is symmetrically slidably connected with a movable plate 603, the outer wall of the movable plate 603 is fixedly connected with an extrusion block 604 extending to the inner wall of the groove 3, and the side of the movable plate 603 away from the extrusion block 604 is fixedly connected with a tooth plate 605, the top of the vertical pole 2 is rotatably connected with a rotating block 608, the bottom end of the rotating block 608 is fixedly connected with a connecting shaft 607, the bottom end of the connecting shaft 607 is fixedly connected with a spur gear 606, and the tooth plate 605 is in contact with the spur gear 606.

[0024] In this embodiment, when installing the sound insulation screen 4, the vertical pole 2 is fixedly connected to the top of the concrete anti-collision wall 1, and then the sound insulation screens 4 are sequentially placed into the grooves 3 on both sides of the vertical pole 2. Multiple sound insulation screens 4 are arranged in sequence up and down. After completion, the rotating block 608 is rotated. The rotating block 608 rotates and drives the connecting shaft 607 to rotate. The connecting shaft 607 rotates and drives the spur gear 606 to rotate. The spur gear 606 rotates and drives the tooth plate 605 to move. The tooth plate 605 moves and drives the movable plate 603 to move. The two movable plates 603 move in opposite directions in the movable groove 602, driving the extrusion blocks 604 on both sides to move into the groove 3. The extrusion blocks 604 move and contact the connecting block 601, generating a downward extrusion force on the connecting block 601. The downward movement of the connecting block 601 drives the sound insulation screen 4 downward. The downward movement of the sound insulation screen 4 causes the multiple sound insulation screens 4 to be pressed against each other, preventing gaps from being generated between the sound insulation screens 4.

[0025] Please refer to Figures 5-6 The mounting mechanism 6 also includes a mounting plate 609, which is fixedly connected to both sides of the sound-absorbing and sound-insulating board 5. A through hole 610 is provided on the outer wall of the mounting plate 609, and a threaded hole 611 is provided on the outer wall of the vertical rod 2. One end of the threaded hole 611 extends to the inner wall of the movable groove 602, and a fixing bolt 612 is connected to the inner wall of the threaded hole 611.

[0026] In this embodiment, during the compression of the sound insulation screen 4, the movable plate 603 slides in the movable groove 602. When the sound insulation screen 4 is compressed, the movable plate 603 moves over the threaded hole 611. After completion, the sound absorbing and sound insulation board 5 is installed. The sound absorbing and sound insulation board 5 is attached to the bottom end of the sound insulation screen 4. The mounting plate 609 is attached to the outer wall of the vertical pole 2. The through hole 610 is aligned with the threaded hole 611. The fixing bolt 612 is passed through the through hole 610 and connected to the fixing bolt 612 to fix the sound absorbing and sound insulation board 5. During the tightening of the fixing bolt 612, the fixing bolt 612 moves into the movable groove 602 and contacts the side of the movable plate 603 away from the extrusion block 604, preventing the movable plate 603 from moving in the opposite direction, thereby fixing the movable plate 603 and preventing the sound insulation screen 4 from loosening. This facilitates compression between the upper and lower sound insulation screens 4 and prevents the formation of a gap that affects the use effect of the sound insulation screen 4.

[0027] Please refer to Figures 1 to 4 The outer wall of the sound insulation screen 4 fits with the inner wall of the groove 3 , the inner wall of the movable groove 602 fits with the outer wall of the movable plate 603 , and the outer wall of the tooth plate 605 is provided with a tooth groove, which meshes with the spur gear 606 .

[0028] In this embodiment, the sound insulation screens 4 are sequentially placed into the grooves 3 on both sides of the uprights 2, and multiple sound insulation screens 4 are arranged in sequence up and down. After completion, the rotating block 608 is rotated, and the rotating block 608 rotates to drive the connecting shaft 607 to rotate. The connecting shaft 607 rotates to drive the spur gear 606 to rotate. The spur gear 606 rotates to drive the tooth plate 605 to move. The displacement of the tooth plate 605 drives the movable plate 603 to move.

[0029] Please refer to Figures 1 to 4 A displacement groove is provided between the groove 3 and the movable groove 602 , the inner wall of the displacement groove is in contact with the outer wall of the extrusion block 604 , and an inclined surface is provided on one end of the extrusion block 604 facing the groove 3 .

[0030] In this embodiment, the two movable plates 603 move in opposite directions in the movable groove 602, driving the extrusion blocks 604 on both sides to move toward the groove 3. The extrusion blocks 604 move and contact with the connecting block 601, generating a downward extrusion force on the connecting block 601. The downward movement of the connecting block 601 drives the sound insulation screen 4 to move downward.

[0031] Please refer to Figures 5-6 The outer wall of the screw of the fixing bolt 612 matches the inner wall of the through hole 610 , and the fixing bolt 612 matches the threaded hole 611 .
